Spring Hinge MIM

The concept by Tag Heuer was to produce spectacles without edges and corners that look like they have been formed from a mould. The edgeless hinge movement was designed as two disk-shaped forms that slid over each other.MIM technology was the only possibility here as the complexity of the component made production via conventional metal-removing processing too expensive. Tolerances meant that the form required could not be produced via waste-wax casting but only via MIM.
